High temperature galvanizing (also called delta galvanizing) is a hot-dip coating process where steel is dipped in a zinc bath at 1040-1165°F (560-630°C)to form a coating comprised of a thin gamma layer with a compact delta layer on top. As a result,a very hard,rough,and thin coating is produced with similar properties to a traditional hot-dip galvanized coating.High Temperatur ...
Hot-Dip Galvanizing Performance in Extreme Temperature. The temperature of the air can have a significant effect on the corrosion rate of some materials, but hot-dip galvanized steel does not show significant differences at very low temperatures, below -40 F, or very high temperatures, above 150 F.. However, very high temperature environments can have an affect on galvanized steel.(plate) What are the characteristics of a hot dip zinc coating?What are the characteristics of a hot dip zinc coating?COATING CHARACTERISTICS The hot dip coating process assures a tightly adherent, uniform coating of zinc on both sides of the product.

For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used.(plate) HOT DIP GALVANIZED - AK Steel(steel) HOT DIP GALVANIZED STEEL Tables TABLE 4 SAE SPECIFIED PROPERTIES NOT COVERED BY ASTM Quality Designation Description Min.
